The Intel Extreme Masters (IEM) is a series of international esports tournaments held in countries around the world. These Electronic Sports League (ESL) sanctioned events, sponsored by Intel, as of 2024 currently host events in Counter-Strike 2 and StarCraft II. Other game titles were hosted in the past. The body that owns the league is Savvy Games Group. The League has operated 17 seasons as of 2023. The highest tier of events, known as Masters Championships, are held in the summer in Cologne, Germany and in the new year in Katowice, Poland and offer the most prize money. Other events, known as Masters events, are held in numerous cities around the globe, which have included Dallas, Shanghai and Sydney.
The Intel Extreme Masters are a product of the ESL. In 2006, when the Intel sponsored European tournament saw room for expansion outside of Europe, especially in North American markets, Intel provided funds for a worldwide tournament, billing it as the Intel Extreme Masters. In 2007, when established, the IEM established a format of many smaller qualifying events, leading up to a large final event that is held at CeBIT. All of the Grand Finals have been held at CeBIT. Starting in 2008, the Tournament was billed as being worldwide, boasting participants from Europe, North America, and Asia. Although Counterstrike 1.6 was the only game offered in the first season, the variety of games has increased greatly, to the four that were offered during Season 5. World of Warcraft was offered during Season 4, but was dropped for Season 5. The Season 5 Finals will be held at CeBIT and will included a US$130,000 prize pool.
